On the Performance of the DNPS-Based Relay Networks under Masquerading Attack

(a) Outage probability and (b) average end-to-end capacity with respect to for the infected relay-assisted cellular network under the exponential and CELN channel environments, where . Also, relays are fixed at middles of the sector as illustrated in Figure 5(a). Therein, the radius of the cell is m, and the location of the mobile station (MS) is uniformly distributed over the sector’s coverage area, while the minimum distance between the MS and base-station (BS) is 50 m. The transmission power of the source (i.e., the MS) is set so that the thermal noise outage () at the destination (i.e., the BS) can be 0.2 as the MS is at the cell edge [19]. Similarly, the transmission power of each relay is set so that can be achieved at the BS. The required SNR corresponding to is defined as dB, whereas, for the purpose of evaluating the outage probability, the SNR threshold is set at dB. The results are obtained by averaging over 200,000 simulation rounds.
